At no load the armature current is 5 amp. If the effect of armature reaction has reduced the air-gap flux 2 percent from no load to full load, determine the no-load speed. The armature resistance is 0.15 ohm. (b) The rated line current of a 230-volt shunt motor is 56 amp. If the shunt-field circuit resistance is 230 ohms and the armature circuit resistance is 0.15 ohm, what would be the line current, assuming that the motor, at standstill, is connected across rated voltage ? How much external resistance must be connected in the armature circuit to limit the current at starting to 125 percent full-load armature current ?\",\"src\":\"stemez-ElectricalMachines\"}","display_format":"text","language":"","answer_status":"published","assets":[],"source_url":"https://huggingface.co/datasets/TIGER-Lab/MMLU-Pro","history":"initial import","indexing_mode":"index","subproblems":[],"grids":[]}
